Smith and Minta A. Smith, Wauwatosa, Wis. Application October 30, 1933, Serial No. 695,762 3 Claims. (01. 184-103 This invention relates to an improvement in lubricators adapted for supplying the proper amount of lubricant to various types of bearings v and in its present embodiment the invention is particularly adapted for average industrial service.

Among the objects of the invention are to provide a lubricator of this character, simple, du-

rable and yet compact and of lightweight construction, one which is efiicient and reliable in operation and yet requires no attention or adjustment. The lubricator may be employed with equal advantage as a constant level lubricator for use with oil wells or anti-friction bearings and as a wick feed lubricator for the sleeve type of bearing. It may be employed either selectively for these purposes or they may be utilized to function simultaneously in feeding the correct amount of lubricant to several different types,

of such bearings.

Another object of the invention is to provide a lubricator having these advantages and capacities and yet lends itself to equivalent and economical manufacture.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying-drawings, forming a part of this specification, and in which:

Figure 1 is a view partly in side elevation and partly in transverse vertical section showing a lubricator embodying the present invention;

Figure 5 is a view similar to Figure 1 but showing another embodiment of the invention;

5 Figure 6 is a view in vertical section taken on line 6-6 of Figure 5; and

Figure '7 is a view in horizontal section taken on lines 1-1 of Figure 5 with parts broken away to more clearly show the construction.

50 Referring to the drawings, and more particularly to Figures 1 to 4, inclusive, it will be seen that the lubricator comprises a cup or base fitting designated generally at I, the cup I having a body portion 2 formed interiorly with an 55 oil chamber 3, there being an opening 4 above the oil chamber 3 to receive the collar 5 that surrounds the lower end or neckli of a main container or reservoir 1.

The container or reservoir 1 may be in the form of an inverted jar and it is united to its collar 5 5' by a layer of suitable plastic designated at 8 and which may be porcelain or the like..

The collar 5 is flanged as at 9 so as to engage the top of the base fitting and support the container I in position and this flange 9 has a flanged 10 lateral extension [0 to provide a top or cover for the lateral extension ll of the base fitting.

Vertical openings l2 and I3 are provided in the lateral extension of the base fitting, the opening l2 forming a continuation of the oil 15 chamber and the opening l3 a standpipe as well as a wick feed outlet. A portion of the collar 5 extends across and blocks the communication of the opening 12 with the opening 4. The lower end of the neck of the reservoir 1 determines 20 and controls the oil level in the oil chamber and in the construction illustrated the collar 5 also terminates at the oil level.

As illustrated, the opening l3 extends down through the bottom of the fitting and has its 25 lower end internally threaded as at [4 to adapt. it for connection with a pipe leading to an air screen intake or to a bearing. A wall [5 separates the openings [2 and I3 of the extension for the greater part of their length but termia0 nates short of the upper ends of the openings so as to afford a communicating passage Hi therebetween. The base fitting is also provided with one or more peripheraloutlets I1 and a bottom outlet 3, either one or bothof which may be employed. When not employed they may be conveniently capped or plugged.

The outlet Il may be connected by a suitable pipe to an oil well type'of bearing whereas the outlet l8 might be connected by means of a U- 40 shaped pipe with an anti-friction type of bearing. Where-the outlet [4 is connected to a sleeve type of bearing, a wick' I9 is provided and has a portion immersed in the oil in the oil chamber and is then extended up through the opening I2, across the upper end of the wall l5 and down through the standpipe l3. To facilitate assembly of a container I with the base fitting and avoid spilling of oil, a stopper 20 may be provided and consists of a cone of resilient sheet 60 metal which is split, at spaced points as indicated at 2| and which has a stop or handle 22 connected therewith. When a container with oil therein is inverted and disassembled from the base fitting the cone drops down into the neck stopper with the neck results in a contraction of; the resilient cone and an effective closing or the Assembly of the stopper with the reservoir is also taken care of. by the flexure of the resilient sections of the stopperwith respect to,

each other.

The form of the invention shownwin. Figures v to 7, inclusive, is identical with that just described and the above description'applies thereto with the exception of the manner in which theextension of the base fitting is constructed. The ex,- tension which is designated at 25 is formed with three openings instead of two, the openings being designated at 26, 21, and 28 and being separated from each other for the major portion of their length by means of walls 29 and 3B. These walls 29 and 3t] terminate short of the upper ends of the openings to provide connecting passages 29' and 36' therebetween. The outside openings 26 and 28 provide the standpipes and'extend down through the bottom of the fitting and also have.

their lower portions internally threaded as indicated at 3|. The intermediate opening 21 forms a continuation of the oil chamber as before.

With this construction, the lubricator is adapted to provide a wick feed of oil to two sleeve type bearings, wicks 33 and 34 being extended from the oil chamber up over the walls 29 and 3fl and down, through the standpipes 26 and 28. Both embodiments of the invention may be advantageously employed to lubricate a plurality of bearings, even though the bearings'be ,of' difierent types, the outlet I! may have a straightj horizontal type connection with an oil well typeof bearing and aiTords a constant uniform feed of oil thereto. Simultaneously with this action the outlets l8 may be employed to supply lubricant to anti-friction types of bearings and the standpipes 13, 26 and 28 may be employed to supply a Wick feed of lubricant to sleeve type bearings.

The construction is highly compact and very simple and yet is rugged and durable. No complicated adjustments are required or possible and yet efficient lubrication is insured. Furthermore, the cups and their collars which serve as caps or covers therefor may be produced by die casting and such is the preferred mode of production.

While I have shown and described several types of'construction in which the invention may be embodied, it is to be understood that the coriher, said cup having a. lateral extension formed thereon, spaced vertical openings in said extension, one of said openings extending from the top of the cup through the bottom thereof, another of said-openings extending from the top of said cup tosaid oil chamber, there being a communicating. passage between said vertical openings above said chamber, a collar having a. portion fitable within said reservoir receiving opening and having a flanged portion engaging and covering the top of said cup and said lateral extension, andan inverted reservoir united to said collar and having a single opening therein, said'collar coacting with said cup to position said reservoir so as to control the level of oil in said chamber, said chamber having an outlet below the levelof oil therein for connection with oil well type bearings, a capillary wick extending between said verticalopeningswhereby one of said openings maybe connected with sleeve type bearings, the entrance of air to said oil chamber being through such one of said openings.

2. A lubricator comprising a cup havinganoil level control chamber, an outlet from said chamber below the level of oil therein for connection with Well type bearings, an outlet from said chamber above the level of oil therein, a wick extending from said chamber below oil level to said last named outlet whereby said outlet may be connected to supply'oil to sleeve type bear- 40 ings, a cover for said cup having a collar extending within saidchamber to secure said cover in position, and an invertedoil reservoir having a single opening secured within said collar whereby said cover and collar react with said cup 7 to fixedly position said reservoir with its opening so related to said chamber as to maintain a fixed oil level therein.

3. The invention defined in claim 2 and further characterized by an inverted cone of resilient sheet metal having a diameter of a size larger than the opening in the reservoir, said cone beingcompressed and inserted within said reservoir, through said opening to act as a stopper therefor,

a depending stem on said cone extending from said reservoir and of suificient length to contact the bottom of the oil chamber to raise said cone free from said opening when said reservoir is positioned asset forth in claim 2.
